MLB DFS Picks: DraftKings 8-Game Main Slate for September 14
DraftKings MLB picks for the eight-game September 14 main slate: Reid Detmers, Padres stacks, Mets and Cubs alternatives, value bats and tournament construction.
By 
Monday’s MLB DraftKings DFS main slate starts at 7:07 p.m. ET on September 14, 2026, with eight games and one obvious decision: how much San Diego do we want at Coors Field? The Padres are our preferred offense, but building the same expensive stack around the same two pitchers is not the only way to attack this slate.

Our starting point is Reid Detmers on the mound, Jackson Merrill in the outfield and a deliberate choice between a full Padres stack and a less obvious offense. These are pregame picks for expected starters, not a claim that batting orders have been announced.

Which games are on the 7:07 p.m. main slate?
| Matchup | Start | Probable pitchers |
|---|---|---|
| Detroit at Toronto | 7:07 p.m. | Troy Melton vs. Jose Soriano |
| Baltimore at New York Mets | 7:10 p.m. | Brandon Young vs. Jonah Tong |
| New York Yankees at Minnesota | 7:40 p.m. | Will Warren vs. Dean Kremer |
| Atlanta at Chicago Cubs | 7:40 p.m. | Reynaldo Lopez vs. David Peterson |
| San Francisco at St. Louis | 7:45 p.m. | Landen Roupp vs. Quinn Mathews |
| San Diego at Colorado | 8:40 p.m. | Casey Mize vs. Tomoyuki Sugano |

| Miami at Arizona | 9:40 p.m. | Sandy Alcantara vs. Corbin Burnes |
The earlier White Sox-Guardians and Dodgers-Reds games are not included. That matters for both pitching and stacking: an attractive player from either matchup does not belong in this main-slate pool. Matchups follow the September 14 game board.
Best DraftKings pitchers
Reid Detmers, Angels vs. Mariners, $8,800
Detmers is the pitcher we want most often. His most recent outing produced six scoreless innings and nine strikeouts against Boston, showing the kind of strikeout-driven ceiling that matters on DraftKings. That performance supports the upside case; it is not a promise that he repeats it against Seattle. Reuters game report.
The construction is the bigger selling point. We can get access to that ceiling without spending five figures at pitcher. Pairing Detmers with a midrange SP2 still leaves room for a serious stack instead of eight hitters chosen primarily because they are cheap.
CTS call: accept the likely popularity. If the lineup needs differentiation, change the second pitcher or the offense before automatically removing our favorite arm.
Landen Roupp, Giants at Cardinals, $7,900
Roupp is our first fit alongside Detmers in a balanced build. His 139 strikeouts in 150 2/3 innings suggest useful production rather than an overwhelming strikeout advantage, and the 72 walks are a real reason not to describe him as risk-free. The attraction is a manageable price in a matchup outside the slate’s biggest run environments. DraftKings salary and pitcher board.
Detmers and Roupp cost $16,700 combined, leaving $33,300 for eight hitters. That is a workable foundation for San Diego exposure without forcing every remaining position into the minimum-price tier.
Quinn Mathews, Cardinals vs. Giants, $7,700
Mathews is the more volatile alternative. His major-league sample is only 30 2/3 innings, with 28 strikeouts and 14 walks, so this is not an established ace hiding at a discount. We are paying for a plausible six-inning, strikeout-supported outcome against San Francisco while accepting that poor command can erase it quickly. DraftKings pitcher breakdown.
The $200 difference from Roupp is not enough to drive the decision by itself. Use Mathews because you prefer his matchup or tournament path, not because an extra $200 automatically makes the lineup better. Detmers-Mathews costs $16,500.
Pitching restraint: we are not building our primary lineups around either starter in Yankees-Twins. Rain can create more than a postponement problem: an extended interruption can also end a starter’s outing. Likewise, neither Coors starter belongs in our main pitching core.
Best MLB stacks and alternatives to Coors
1. San Diego Padres at Colorado Rockies
| Player | DK position | Salary |
|---|---|---|
| Jackson Merrill | OF | $5,500 |
| Fernando Tatis Jr. | 2B/OF | $7,000 |
| Manny Machado | 3B | $6,000 |
| Jake Cronenworth | 1B/2B | $4,000 |
| Xander Bogaerts | SS | $4,800 |
Preferred salary-adjusted entry: Merrill and Cronenworth. Tatis and Machado are the premium additions when San Diego is the main offense we are funding. Bogaerts is another stack option, but these five players are a pool, not a requirement to roster all five together.
The matchup puts San Diego against right-hander Tomoyuki Sugano at Coors. Merrill’s left-handed bat is our favorite way into it at $5,500. The game carries a 10.5-run total on the main-slate matchup board, which helps explain why we expect the Padres to attract attention.
We are comfortable treating San Diego as good chalk. The bad version is assuming that any five Padres, plus the most obvious salary relief, automatically make a good tournament lineup. A full stack needs the offense to keep producing across multiple spots in the order. A Merrill-Tatis mini-stack needs fewer things to go right and leaves room for another team to do the heavy lifting.
The salary catch: those five Padres cost $27,300. Add Detmers-Roupp at $16,700 and only $6,000 remains for three hitters. That is a minimum-price finish, not a balanced build. We prefer a smaller Padres group when paying for a second strong offense.
2. New York Mets vs. Baltimore Orioles
| Player | DK position | Salary |
|---|---|---|
| Francisco Lindor | SS | $4,600 |
| Juan Soto | OF | $6,100 |
| Brett Baty | 3B/OF | $2,800 |
Preferred core: Lindor and Soto, with Baty as the salary-saving left-handed extension if he starts. The Lindor-Soto pair costs $10,700, while Baty can help connect the expensive pieces without requiring every hitter to carry a premium salary.
Lindor costs $4,600 and gives us a strong alternative to spending every meaningful dollar at Coors. Against Brandon Young, we prefer concentrating on the Mets’ left-handed and switch-hitting paths rather than adding unrelated hitters simply to reach a five-man stack. The salary comes from DraftKings’ September 14 hitter board.
This is our favorite two-player complement to San Diego. It is also a reasonable full-stack direction for a tournament entry that deliberately fades the Coors game. The trade-off is straightforward: we are giving up the stronger run environment in exchange for a different way to capture an offense’s productive innings.
3. Chicago Cubs vs. Atlanta Braves
| Player | DK position | Salary |
|---|---|---|
| Ian Happ | OF | $3,700 |
| Michael Busch | 1B | $4,200 |
| Seiya Suzuki | OF | $5,000 |
| Pete Crow-Armstrong | OF | $6,500 |
Preferred salary-adjusted core: Happ, Busch and Suzuki at $12,900 combined. Crow-Armstrong is the premium extension, not automatic salary relief. At $6,500, he belongs in a build that deliberately pays for Chicago’s ceiling rather than assuming every non-Coors hitter is inexpensive.
The Cubs offer a second full-stack route outside Colorado against Reynaldo Lopez. We like using Chicago as the main offense in a separate tournament build, rather than putting one Cub into a Padres lineup and calling the whole thing contrarian. A stack benefits when traffic turns into a big inning, not just when one hitter goes deep.
Do not carry yesterday’s Wrigley assumptions into this game. The forecast calls for a crosswind, not a simple wind-blowing-out boost. Chicago is a hitting alternative, not a weather-based free square.
Priority bats and salary relief
| Player | Team | DK salary | Best use |
|---|---|---|---|
| Jackson Merrill | SD | $5,500 | First Coors hitter into our builds |
| Francisco Lindor | NYM | $4,600 | Non-Coors priority and Mets stack anchor |
| Josh Smith | TOR | $2,200 | Salary relief if in the starting lineup |
Smith is a Blue Jays option tonight, with 2B/3B eligibility on DraftKings. At $2,200, his job in our lineup is to preserve access to better pitchers and a stronger offensive core. His expected real-life outfield assignment does not make him eligible at OF in the contest. His appeal is salary-adjusted, and a lower batting-order position would keep the plate-appearance ceiling modest.
Good chalk, leverage and the weather decision
Our ownership discussion is a qualitative CTS assessment, not a numerical projection feed. We expect the Coors environment and accessible Detmers salary to be popular, but we are not attaching unsupported percentages to them.
- Good chalk: Detmers and the Padres’ main hitters. Their popularity would be understandable.
- Weak construction: combining every popular piece with the same cheap fillers and no clear offensive correlation.
- Useful leverage: a Mets or Cubs primary stack, or Mathews as the second pitcher, while retaining another strong mainstream play.
- Risk, not automatic leverage: Yankees-Twins. The elevated rain forecast makes this a conditional tournament game, not a clever way to manufacture low ownership in a conservative lineup.
The weather and expected-lineup board supports the Minnesota caution. A rain percentage alone is not proof of a postponement, but our primary builds do not need that additional uncertainty.
How we are building tonight
Single-entry starting point: Detmers-Roupp, Merrill-Cronenworth and Lindor-Soto. Those six players cost $36,900. Using Cronenworth at 1B leaves $13,100 for C, 2B, 3B and one OF. That is a legal core with room for additional correlation and salary relief, not a finished lineup. Smith can fill 2B or 3B if he starts; Baty can fill 3B or OF.
Large-field alternative: Detmers-Mathews with a Cubs or Mets primary stack and a smaller Padres piece. That changes an important part of the lineup without requiring every choice to be uncomfortable.
Those are construction frameworks, not complete ten-player lineups. The core recommendation is simple: start with Detmers, prioritize Merrill, and decide intentionally whether San Diego is your full stack or your smaller exposure. We want correlated upside, not eight disconnected names that happen to fit under the cap.
